Docker Compose setup for Django/Postgres app.

Django in Docker

Docker Compose setup for Django/Postgres app. Based on the tutorial from the Docker documenation.

Prerequisites

Docker and Docker Compose are required to be installed in your system.

Usage

Start your Django project with:

docker-compose run web django-admin startproject <your_project> .

Update DATABASES contant in settings.py module to point at the Postgres container:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'postgres',
        'USER': 'postgres',
        'PASSWORD': 'postgres',
        'HOST': 'db',
        'PORT': 5432,
    }
}

Also update ALLOWED_HOSTS contant in settings.py module:

ALLOWED_HOSTS = ["*"]

Run the containers:

docker-compose up

Open your browser and navigate to http://0.0.0.0:8000. If you see the congratulations page then you are all set.

Troubleshooting

If during the execution of the command docker-compose up you see an error like this:

python: can't open file '/code/manage.py': [Errno 2] No such file or directory

Then you need to update the path to manage.py module in docker-compose.yml file:

command: python manage.py runserver 0.0.0.0:8000
